DETAILED DESCRIPTION

[0019] ​The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, a multi-functional trolley for airports includes a base plate 1, a push handle 2 on the top of the base plate 1, a toothed plate 3 fixedly connected to the top of the base plate 1, a side surface of the push handle 2 that fits against one side of the toothed plate 3, a fixing shell 4 and a connecting frame 5 respectively on both sides of the toothed plate 3, both ends of the connecting frame 5 being fixedly connected to one side of the fixing shell 4, the inner wall of the connecting frame 5 fitting against the side surface of the push handle 2, a sliding plate 6 slidably connected inside the fixing shell 4, a locking block 7 fixedly connected to one side of the sliding plate 6, and a spring 9 and a pull handle 8 fixedly connected to the side of the sliding plate 6 away from the locking block 7.

[0021] The side of the latch 7 away from the slide plate 6 extends to the outside of the fixed shell 4 and is in contact with the side of the toothed plate 3 away from the push handle 2. The end of the pull handle 8 away from the slide plate 6 extends to the outside of the fixed shell 4. The end of the spring 9 away from the slide plate 6 is fixedly connected to the inner wall of one side of the fixed shell 4.

[0022] The inner wall of the connecting frame 5 is fixedly connected with a post 21, which is inserted into the inside of the push handle 2. The bottom four corners of the base plate 1 are all fixedly connected with casters.

[0023] The height of the push handle 2 of this trolley is adjustable. When the height of the push handle 2 is increased, the base plate 1 can be stepped on and the push handle 2 can be pulled upwards directly. Due to the restriction of the fixed shell 4 and the connecting frame 5, the push handle 2 can move to one side of the upper toothed plate 3. During the movement of the push handle 2, the inclined surface of the locking block 7 will continuously contact the inclined surface of the toothed plate 3. The inclined surface of the toothed plate 3 will squeeze the inclined surface of the locking block 7, so that the locking block 7 can retract into the fixed shell 4. When the push handle 2 is moved to a suitable height, the spring 9 can push the locking block 7 through the slide plate 6, so that the plane of the locking block 7 abuts against the plane of the toothed plate 3, thereby fixing the push handle 2 and improving the stability of the push handle 2. When the height of the push handle 2 is decreased, the pull handle 8 needs to be pulled first. The pull handle 8 can drive the locking block 7 to retract into the fixed shell 4 through the slide plate 6, so that the plane of the locking block 7 separates from the plane of the toothed plate 3. At this time, the push handle 2 can be pressed down directly to decrease the height of the push handle 2.

[0024] Furthermore, in order to improve the stability of luggage, such as Figure 1 , Figure 2 and Figure 5As shown, a slide rod 10 is fixedly connected to the top of the base plate 1, a lifting plate 11 is slidably connected to the side surface of the slide rod 10, and a limit block 18 is fixedly connected to the top of the slide rod 10.

[0025] A first connecting block 13 is symmetrically connected to one side of the lifting plate 11. A pressure plate 12 is provided on one side of the lifting plate 11. A second connecting block 14 is fixedly connected to the side of the pressure plate 12 near the lifting plate 11. Insert rods 15 are fixedly connected to both sides of the second connecting block 14. The insert rods 15 are inserted into the inside of the first connecting block 13.

[0026] A limiting frame 16 is fixedly connected to the top of the base plate 1, and multiple limiting plates 17 are fixedly connected to the bottom of the pressure plate 12.

[0027] The lifting plate 11 can move on the slide bar 10. The setting of the limiting block 18 reduces the possibility of the lifting plate 11 falling off the slide bar 10. The pressure plate 12 can rotate on the lifting plate 11 through the first connecting block 13, the second connecting block 14 and the insert rod 15. When luggage is placed on the bottom plate 1, it can be...

[0028] Furthermore, to improve the smoothness of the movement of the lifting plate 11, such as... Figure 1 , Figure 2 and Figure 5 As shown, an auxiliary groove 19 is provided on the lifting plate 11. A rotating shaft is fixedly connected inside the auxiliary groove 19. A roller 20 is rotatably connected to the side surface of the rotating shaft. The side surface of the roller 20 is in contact with the side surface of the slide rod 10.

[0029] When the lifting plate 11 moves on the slide bar 10, the roller 20 will also roll on the shaft due to friction to assist the lifting plate 11 in moving. The setting of the roller 20 effectively reduces the friction when the lifting plate 11 moves and improves the smoothness of the lifting plate 11's movement.

[0030] Working principle: the trolley in use, need first rotate the pressing plate 12, make the pressing plate 12 keep vertical state, luggage is placed to the inside of the limiting frame 16 after, can according to the height of luggage moves the lifting plate 11, when the bottom of lifting plate 11 is higher than the top of luggage, can rotate the pressing plate 12 and make it restore to initial state, then release the lifting plate 11, under the action of gravity, lifting plate 11 and pressing plate 12 will automatically fall in the top of luggage, thereby limiting luggage, when the height of push handle 2 is adjusted, can use foot to tread the bottom plate 1, then directly pull up push handle 2, the inclined plane of clamping block 7 will constantly contact with the inclined plane of toothed plate 3 in the process of push handle 2 movement, the inclined plane of toothed plate 3 will extrude the inclined plane of clamping block 7, make clamping block 7 can shrink to the inside of fixed shell 4, when push handle 2 moves to the appropriate height, spring 9 can push clamping block 7 through slide plate 6, make the plane of clamping block 7 and the plane of toothed plate 3 abut, thereby realize the fixation of push handle 2, when the height of push handle 2 is adjusted, then need pull the handle 8, handle 8 can drive clamping block 7 to shrink to the inside of fixed shell 4 through slide plate 6, make the plane of clamping block 7 and the plane of toothed plate 3 separate, at this time, push handle 2 can be directly pressed down to adjust the height of push handle 2.

[0031] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art, according to the technical scheme and the utility model concept of the present application, within the technical range disclosed by the present application, makes equivalent replacement or change, should be covered in the protection scope of the present application.
